Data Bus Width Specification

Specify the data bus widths of spaces.

00: Reserved (setting prohibited)

01: 8-bit size

10: 16-bit size

11: 32-bit size

For MPX-I/O, selects bus width by address

Notes:

1. The initial data bus width for areas 3 to 6

is specified by external pins. The BSZ[1:0]

bits settings in CS0BCR are ignored but

the bus width settings in CS1BCR to

CS7BCR can be modified.

2. If area 5 or area 6 is specified as PCMCIA

space, the bus width can be specified as

either 8 bits or 16 bits.

3. If area 3 is specified as SDRAM space,

the bus width can be specified as either 16

bits or 32 bits.

8 to 0



All 0

Reserved

These bits are always read as 0. The write value

should always be 0.

Note:

CSnBCR samples the external pins (MD_BW) that specify the bus width at power-on

reset.
